I have had more canker sores than anybody. And they've been huge too. I have scars on the inside of my mouth from canker sores I had years ago. I had one in freshman year in high school that lasted at least two months. It was so big
I COULDN'T EAT WITH A FORK. There's still a huge ass bump where it used to be.
Ibeprofun (or however you spell it) can cause canker sores, so if you've been taking that, stop. Just take aspirin or tylenol.
I have found the three best things to do for a canker sore:
1. Lydocaine. You can actually go to a doctor and get it for your canker sore (exaggerate though. Say you get them
all the time) It's like a gel, you rub it on your canker sore. But be careful not to rub it on anything else, as it feels like novacaine. It really, really numbs the canker sore. It's great.
2. Cold medicene. Anything, Nyquil, robitussein, any kind of cold medicene. Just rub some on your canker sore. Because cold medicenes kill bacteria, and canker sores hurt because of bacteria, or something like that. I forget why, but it really makes them feel better. Mouth wash too. Mouthwash stings at first, but it won't hurt for a while afterwards.
3. Rubbing it with your finger. I can't remember why, but if you rub it with your finger, it makes the pain go down and it makes it heal faster. It does too. But I can't remember how that works.
I've had too many cankersores.
